Draught
The draught in the stove is crucial to have a good performance in specific adverse weather
conditions (rain, fog, snow, altitude, cold, wind), and it is conditioned by the position of the fuel.
Adverse weather conditions that impact negatively on the draft are manifold; particularly
burdensome is the wind, which can be: ascending, horizontal, descending.
-
Ascending wind increases the depression and consequently the draught.
-
Horizontal wind: it increases the depression, only in the case of a successful installation in
the direction of the wind.
-
Descending wind decreases the depression and consequently the draught.
The flue, if disposed on the upwind side, increases the overpressure and consequently, in the
opposite situation, increases the depression, decreasing the draught.
To overcome these drawbacks, the installer must act directly on the stove, modifying the parameter
to adjust the speed of fume extraction and conduct a review of all safety devices. This is particularly
delicate, it must always be carried out by authorized personnel. The ZF company disclaims any
liability, whether civil or criminal, for failure to control by the installer with all safety devices.
